I have the following information:
\[n=p^2q\]
\[k \ge 4\]
\[0<v<n\]
\[0 \le x < pq\]
\[y=\lceil \frac{(vx^k) \mod n}{pq} \rceil \cdot (kx^{k1})^{1} \mod p\]
I want to show:
\[\sum_{i=0}^{k}\left(\begin{matrix} k \\ i \end{matrix}\right) x^{k1}(ypq)^i \equiv x^k+kypqx^{k1}\]
the congruence is mod n

Best ResponseYou've already chosen the best response.0i made a mistake \[\sum_{i=0}^{k}\left(\begin{matrix} k \\ i \end{matrix}\right) x^{ki}(ypq)^i \equiv x^k+kypqx^{k1}\] I'm trying to follow a proof but i don't know how they got from that one part to the other part

Best ResponseYou've already chosen the best response.0ask me next semester when I've taken cryptography, and I might be able to help you, but right now, I haven't got a clue.

Best ResponseYou've already chosen the best response.2only the first two values of i will matter (i=0,1) for i>1 you have a \((pq)^2\) part which is \(p^2qq=nq\) which is zero nod n

Best ResponseYou've already chosen the best response.0i don't see this (pq)^2 part

Best ResponseYou've already chosen the best response.2\[{k\choose i}x^{k1}(ypq)^i\] for \(i\ge2\) \[{k\choose i}x^{k1}(ypq)^i={k\choose i}x^{k1}(y^i)(pq)^{i2}p^2qq\] \[=\left({k\choose i}x^{k1}(y^i)(pq)^{i2}q\right)\times n\]

Best ResponseYou've already chosen the best response.0you are so smart to notice the first two values will only matter since n mod n is like totally 0 thanks zarkon

Best ResponseYou've already chosen the best response.0is there any number theory in abstract algebra i can't remember

Best ResponseYou've already chosen the best response.0not very much. I'm taking intro to number theory, and cryptography next semester.

KingGeorge

Best ResponseYou've already chosen the best response.0It certainly sounds fun. I'm definitely enjoying my abstract algebra class right now. We had the barest hints of some number theory in discrete math so I'm not completely helpless.

KingGeorge

Best ResponseYou've already chosen the best response.0From my experience, I don't like differential equations very much. Granted, I've never had a full course in it, but it just isn't my thing.

Zarkon

Best ResponseYou've already chosen the best response.0I'm personally more of an algebra person. Stats was interesting at first, but then it got boring.

Best ResponseYou've already chosen the best response.0There are some cool things though in stat i do admit

Best ResponseYou've already chosen the best response.0It was the same with calculus for me. Interesting at first, and then it just stopped interesting me.

Zarkon
